COMPUTER SERVER HEAT REGULATION UTILIZING
INTEGRATED PRECISION AIR FLOW
FIELD OF THE INVENTION
The present disclosure relates to a computer server rack and more
particularly, a
computer server rack system that can be used to efficiently direct air flow to
electric
equipment such as servers and other network devices for dissipation of heat.
BACKGROUND
Existing rack-mount server systems include a server rack and a plurality of
server
units received in the server rack. Typically each of the server units is
mounted to the server
rack with a pair of mounting brackets or rails respectively fixed to the
inside surface of
opposite sidewalls of a server rack. There have been numerous efforts to
direct air and other
fluids to electronic equipment to aid in heat dissipation.
SUMMARY
The server rack according to the invention includes a frame that includes
hollow
tubular support posts on the front sides and rear sides of the device. Between
the front and
rear posts are forward side panels and rearward side panels. The panels
receive a
complement of cartridges that have valve members to control the flow of air
from a rear
cavity though passages in the cartridges, through the rail and into servers. A
plurality of
side rails for receiving servers are attached to the front and rear posts. The
rails have
passages through the sidewalls that correspond with passages provided on the
sidewalls
of the servers.
In a preferred embodiment, air conditioned air is introduced to forward side

panels through passages provided on the upper and lower surfaces. Next, air
travels from
the forward panel, though one or more passages that is provided through a
cartridge
member, and then, into a front section of a server through a passage that is
provided on
the lateral sidewall of the server. Air travels through the server from the
front section of
the server to a rear section and then exits through a passage in the lateral
sidewall to a
cartridge that is provided in a rear panel. Next the air is returned to the
air conditioner
unit for recirculation.
In an embodiment the sever rack is approximately 6 feet tall and designed to
accommodate forty-two server units in 4.445 cm (1.75 inch) increments. Rail
members
are provided at each unit segment on the side panels and support a server. In
embodiments
further discussed below, passages through the cartridges have at least one
valve member
that can be individually electromechanically or manually controlled. When no
server is
provided in a specific rack unit, or when the temperature is otherwise
adequately
controlled in a particular server unit, the aperture may be closed. In
embodiments, a
controller automatically opens or closes valve members provide in cartridges
in response
to a signal from a thermometer.
As such, it should be appreciated that the valves or passages can be opened
and
closed variably for each server depending on the cooling needs for the server.
Further,
as discussed herein, the degree of air flow through the aperture can be
controlled using
a damper or weir arrangement. Therefore, in embodiments, a local controller is
provided
and can receive input information from thermometers reading the temperatures
of the
servers and can adjust the opening and closing valves aperture accordingly.
